ASPNetCore - Uploading a file through REST

Question

I am using Insomnia for testing an API, but the same happens with Postman.

I want to test a file upload, with the following controller:

public async          


        

Answer 1

In addition of the above, in case of multipart file conversion to base64String you can refer to the below:

if (File.Length> 0)
   {
       using (var ms = new MemoryStream())
       {
           File.CopyTo(ms);
           var fileBytes = ms.ToArray();
           string s = Convert.ToBase64String(fileBytes);                                    
       }
    }

Note: I am using this code for .NET CORE 2.1
